DSC HS2128 Reference Manual page 52

The Installer and Master codes are system codes. They can be changed but not deleted. The other codes are user-defined
and can be added or deleted as necessary. By default, access codes have the same partition and attribute programming as
the code used to program them.
Access codes are either 4, 6 or 8 digits in length, depending on the setting of programming section [041]. Duplicate codes
are not valid.
Note: EN50131-1 compliant systems using 1000 access codes shall set the access code to 8 digits (section [041], option
02).
Installer Code
This code provides access to Installer Programming [*][8]. The installer code can access all partitions and perform any
keypad function. This code can be programed by the installer in section [006][001]. The default is 5555 (4-digit), 555555 (6-
digit) or 55555555 (8-digit).
EN
Note: For EN50131-1 approved installations the installer code cannot change the master code or any other level 3 codes.
Attempting to access the master code from the installers code generates an error tone from the system.
Master Code - Access Code [0001]
By default the master code can access all partitions and can perform any keypad function. This code can be used to program
all access codes, including the supervisor and duress codes.
If section [015] option 6 is on, the master code can only be changed by the installer via Installer Programming.
The default is 1234 (4-digit), 123456 (6-digit) or 12345678 (8-digit).
The master code can be returned to factory default settings using Installer Programming section [989].
EN
Maintenance Code
The maintenance code can only be used to arm and disarm the system. It cannot bypass zones. Use [*][9] to arm the system,
cancel auto-arming, or perform [*][7] command functions. No arm/disarm bell squawks are sounded when the maintenance
code is used. The Maintenance code can be programed by the installer in programming section [006][003]. The default is
AAAA (4-digit), AAAAAA (6-digit) or AAAAAAAA (8-digit).
User Codes - Access Codes [0002] to [1000]
This type of access code is used to arm and disarm assigned partitions and perform other functions as programmed. It can
access the [*][6] menu if programming option [023] option 8 is on. This code cannot access the [*][5] and [*][8] menus.
User access codes are created by the master user or supervisor users. The default is AAAA (4-digit), AAAAAA (6-digit) or
AAAAAAAA (8-digit).
Supervisor Codes - Access Codes [0002] to [1000]
A supervisor code is a user code with the Supervisor attribute enabled. Users with this attribute can access the [*][5] and [*]
[6] user code programming section for the partition they are assigned to. However, these codes can only program codes
which have equal or lesser attributes. These attributes are changeable via the [*][5] menu. A supervisor code is created by
the master user or other supervisor users.
Duress Codes - Access Codes [0002] to [1000]
Duress codes function the same as user access codes, except they transmit a duress reporting code when used to perform
any function on the system.
Duress codes cannot be used to access [*][5], [*][6] or [*][8] menus.
Duress codes are created by the master user or supervisor users.
